Some first impressions:
Thanks Matt and Jo, for more than a decade you've made great tools and this is the best so far.
Thanks Oshyan for great customer service.
Errors due to unfound files state what they are. Time saved!
(Attached is the result of fixing missing texture references, saving, then reopening the saved file in the same instance of the program. The Errors window was still open when i reopened the file; the errors no longer existed so the window had nothing to display. On closing it and TG, then reopening, no errors.)
